Deletes the queue specified by the queue URL, regardless of whether
the queue is empty. If the specified queue doesn't exist, Amazon SQS returns
a successful response.

Use DeleteQueue with care; once you delete your queue, any
messages in the queue are no longer available.

When you delete a queue, the deletion process takes up to 60 seconds.
Requests you send involving that queue during the 60 seconds might succeed.
For example, a SendMessage request might succeed, but after the 60
seconds, the queue and that message you sent no longer exist. Also, when you
delete a queue, you must wait at least 60 seconds before creating a queue
with the same name.

We reserve the right to delete queues that have had no activity for more than
30 days. For more information, see How Amazon SQS Queues Work in the Amazon SQS Developer Guide.
